Sensitivity Analysis of CPP’s for Solvent Removal Process of a API-Protein Bonded Nano-Suspension

C. C. Huang [1], T. Liu [1], F. Faassen [1],
[1] Teva Pharmachemie B.V., Haarlem, The Netherlands

Solvent extraction and evaporation is a widely used unit operation in the manufacturing of micro and nano-particles. Due to the weak bond of the API to the protein, the product is highly sensitive to temperature, mechanical mixing and extraction/evaporation rate. A slow extraction ... Per saperne di più

Iron Ore Sintering Process Model to Study Local Permeability Control

Y. Kaymak [1], T. Hauck [1], M. Hillers [2],
[1] VDEh Betriebsforschungsinstitute GmbH, Düsseldorf, Germany
[2] Shuangliang Clyde Bergemann GmbH, Ratingen, Germany

The iron ore sintering process prepares fine iron ore for the blast furnace process. A mixture consisting of iron ore, coke (fuel) and additives is ignited at the top and air is sucked from below to move a combustion front down through the bed. Most of the sintering plants use ...
